Description

Brake mechanism for storage battery electric locomotive in coal mine

Technical Field

The invention relates to a brake mechanism, in particular to a brake mechanism for a storage battery electric locomotive in a coal mine, and belongs to the field of electric locomotives.

Background

The electric locomotive is a traction device for rail vehicle transportation, and the power is to drive wheels to rotate by using a traction motor, so that the locomotive runs on a rail by means of the friction between the wheels and a rail surface. The coal mine safety valve has low operation cost and good safety performance, and is widely used in the coal mine industry.

When the electric locomotive runs on the track, the electric locomotive is mainly braked by the brake mechanism, and the performance of the brake mechanism directly influences the brake efficiency of the electric locomotive and the safety of the electric locomotive during braking. Because the mine is full of dust and coal briquettes, after the wheels and the track are mutually extruded, thick coal beds can be generated on the wheels and the track, the wheels are influenced to roll on the track, and the wheels can be derailed from the track in severe cases. When braking, the brake pad is affected by the coal seam, and the contact force between the brake pad and the brake disc is insufficient, so that the performance of braking is reduced. And during the brake, the coal seam probably leads to the wheel to rock, and then makes the electric locomotive drop from the track.
